Abstract: A power outlet includes a base and sliding covers. The base has conductive terminals for electrically connecting to terminals of a power line. The conductive terminals are partially exposed from the base and a pair of first guiding portions arranged in parallel to each other is disposed on each side of the base exposing the conductive terminals. Each of the sliding covers has second guiding portions capable of sliding with and engaging with the corresponding first guiding portions so as to allow the sliding covers to slide relative to the base, thereby shielding the exposed portions of the conductive terminals and preventing accidental touching of the exposed portions of the conductive terminals by a user and thus avoiding the risk of electric shock.

Abstract: A shaft lock socket system comprises: a housing defining a receiving chamber; at least a socket received in the receiving chamber, installed with a gap between the back of the socket and the inward portion of the receiving chamber; and at least an adjusting member arranged in the gap between the socket and the receiving chamber and abutting against the back of the socket. The system allows for adjustment of the tightness between the socket and the housing to a proper level, reducing resonance vibration in response to tiny vibrations caused by current passing through the plug and socket, thus improving the stability of power transmission and the sound quality of an audio device.

Abstract: A reduction projection aligner has a light source accommodated in an air-tight vessel, an optical filter fitted in the air-tight vessel, a reticle provided outside of the air-tight vessel and a reduction projection lens unit provided between the reticle and a photo-sensitive layer, and an evacuating system creates vacuum in the air tight vessel so that undesirable short-wavelength light component, which promotes undesirable reaction for tarnishing the reticle, is eliminated from the light before radiation from the air-tight vessel.

Abstract: An automotive air-conditioner has a motor-driven centrifugal fan and a casing accommodating the fan and having first and second wall portions adjacent to axially opposite open ends of the fan, respectively. A fresh-air inlet and a first recirculated-air inlet are formed in the first wall portion, while a second recirculated-air inlet is formed in the second wall portion to increase flow of recirculated-air sucked into the fan during a recirculation mode of air-conditioner operation. The fresh-air inlet and the first recirculated-air inlet are selectively opened and closed by a servo-actuated damper, while the second recirculated-air inlet is closed and opened by another servo-actuated damper operatively linked to the first-mentioned damper.

Abstract: An air conditioner for a vehicle which has a fan of a centrifugal blower used in the air conditioner, the fan having upper and lower fan secitons split by a shield plate with respect to a rotational shaft direction, a normal air intake port formed at either one side of the upper and lower fan section, an increasing air intake port formed at the other of the upper and lower fan sections, and a damper formed at least in the increasing air intake port, the damper being opened only when air intake quantity is necessarily increased or air intake resistance is necessarily decreased. Thus, the air conditioner can increase the effective air intake volume to raise the efficiency of a blower and to simultaneously obtain sufficient air blowing quantity.
